Abstract:

Initial allocation of water rights is the key point for water management. The optimization of water resource allocation will promote sustainable development of national economy and society. In consideration of efficiency, impartiality and sustainability, affective factors for the initial allocation of water rights were discussed in this paper, including economic development, efficiency of water usage, average water distribution, current water consumption, water resource field preference, ecological environment and social development. In this paper, an index system was founded, and semistructural and multiobjective fuzzy optimal selection model was adopted; the objective weight and relative membership degree of qualitative objectives were calculated depending on practical quantified knowledge. Expert consultation was used to compare the importance of two objectives to ensure the practicability of the model. The relative membership degree of quantitative objectives was calculated by computing formula according to practical situation. By applying the model into Hanjiang river basin, the initial allocation of water rights was performed.

Key words: water right of river basin, initial allocation, multiobjective and semistructural fuzzy optimal selection model, qualitative objective, quantitative objective
